DISPOSABLE RAZOR BACKGROUND OF THE INVENTION" Field of the Invention Thepresent invention relates to disposable razors and is an improvement onmy prior U.S. Pat. No. 2,684,529 issued July 27, 1954 entitledDisposable Raz'or.

SUMMARY OF THE INVENTION A disposable razor is provided with includes arazor blade cemented between the elements of a two-piece head secured toa handle. The blade is secured in the head and the head includes a guardto prepare the skin for the passage of the blade.

The primary object of the invention is to provide a disposable razorwhich is inexpensive to manufacture, simple to use and which isconstructed to prevent skin injury due to contact with the corner oredges of the blade.

Other objects and advantages will become apparent in the followingspecification when considered in the light of the attached drawings.

FIG. 5 is an elevational view of the blade;

FIG. 6 is a transverse sectional view taken along the line 6-6 of FIG. 1looking in the direction of the arrows;

FIG. 7 is a side elevation of the handle structure;

FIG. 8 is an end elevation of a circular handle; and

FIG. 9 is an end elevation of a rectangular handle structure.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings indetail wherein like reference characters indicate like parts throughoutthe several figures the reference numeral 10 indicates generally adisposable razor constructed in accordance with the invention.

The disposable razor 10 includes a head generally indicated at 11 andthe head 11 includes a blade support element 12 of generally rectangularform and having a guard 13 formed thereon with a plurality of alignedelongated slots 14 formed therein to permit the passage of hairtherethrough.

The blade support 12 has a plurality of bores 15 extendingperpendicularly therethrough for reasons to be assigned. A razor blade16 is adapted to engage the blade support 12 and has a plurality ofbores 17 extending perpendicularly therethrough and adapted foralignment with the bores 15. The blade support 12 has generallyrectangular notches 18 formed in the opposite end thereof for alignmentwith generally rectangular notches 19 formed in the opposite ends of theblade 16. The blade 16 has a cutting edge 20 which is adapted to overliethe slots 14 when the blade 16 is in engagement with the blade support12.

A blade cover 21 of generally rectangular form is adapted to engage theupper surface of the blade 16 and has a plurality of alignment pins 22extending perpendicularly therefrom to engage through the bores 17 ofthe blade 16 and through the bores 15 of the blade support 12. The cover21 has generally rectangular notches 23 formed in the opposite endsthereof for alignment with the notches 19 of the blade 16. The

'cover 21 has an edge 24 arranged parallel to the cutting edge 20 of theblade 16 and the edge 24 is spaced away from the guard 13 and from thecutting edge 20 to permit the cutting edge 20 to be exposed sufficientlyto allow shaving therewith.

A handle generally indicated at 25 includes a generally cylindrical handengaging portion 26 which extends integrally from a generally flat neckportion 27. A right angle extension 28 is integrally formed on the neck27 for attachment to the cover 21 of the head 1 l.

The blade support 12, razor blade 16, cover 21 and handle extension 28are secured together by cement which secures the ends of the blade aswell as the sides and back thereof. The construction of the bladesupport 12 protects the corners of the blade to prevent it from cuttingor scratching the face while the structure of the blade support and thecover are such that the proper angle of the blade for the best shavingcomfort is provided.

A modified handle for the razor 10 is indicated generally at in FIG. 9and includes a generally rectangular handle in transverse cross-sectionrather than the cylindrical handle indicated generally at 25.

The handle 125 with the exception of its transverse cross-section isidentical to the handle 25 in every respect.

The alignment notches l8, l9 and 23 are useful for aligning the elementsof the razor 10 during machine assembly thereof.

Having thus described the preferred embodiments of the invention itshould be understood that numerous structural modifications andadaptations may be resorted to without departing from the spirit of theinvention.
